I heard a Doctor say that if a baby is blindfold at birth and the blindfold is then removed, after a certain amount of time the baby will never be able to see. And the reason has to do with the fact that man, with his large brain needed to be as efficient as possible so childbirth would be possible. the software comes AFTER birth for us, as opposed to a horse that does everything it ever does within minutes of its birth.

The eye is the organ of sight and is shaped as a slightly irregular hollow sphere. Various structures in the eye enable it to translate light into recognizable images. Among these are the cornea, the lens, and the retina. Light first passes through the cornea, a clear dome-like structure covering the iris, or colored part, of the eye. The cornea bends, or refracts, the light onto the lens. The light is then refracted a second time while passing through the lens, finally focusing on the retina. The retina is the light sensitive part of the eye. Impulses travel down the optic nerve to the occipital lobe of the brain, which then interprets the image in the correct perspective. The shape of the eye is very important in keeping the things we see in focus. If the shape of the eye changes, it affects a person’s vision. Normally, light is precisely focused onto the retina at a location called the focal point. A nearsighted eye is longer from front to back than a normal eye causing light to be focused in front of the retina instead of directly onto it. This makes it difficult to see objects that are far away. Glasses with concave lenses are used to correct nearsightedness. The concave lens focuses light back onto the focal point of the retina. Farsightedness occurs when the length of the eye is too short. Light is focused at a point behind the retina, making it difficult to see objects that are up close. A convex lens is used to correct farsightedness because it directs the focal point back onto the retina. How Your Eyes Work When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. Rods and Cones in the retina The cornea bends, or refracts, the rays that pass through the round hole of the pupil. The iris (the colored portion of the eye that surrounds the pupil) opens and closes, making the pupil bigger or smaller. This regulates the amount of light passing through. The light rays then pass through the lens, which changes shape so it can further bend the rays and focus them on the retina. The retina, which sits at the back of the eye, is a thin layer of tissue that contains millions of tiny light-sensing nerve cells. These nerve cells are called rods and cones because of their distinct shapes. Cones are concentrated in the center of the retina, in an area called the macula. When there is bright light, cones provide clear, sharp central vision and detect colors and fine details. Rods are located outside the macula and extend all the way to the outer edge of the retina. They provide peripheral or side vision. Rods also allow the eyes to detect motion and help us see in dim light and at night. These cells in the retina convert the light into electrical impulses. The optic nerve sends these impulses to the brain, which produces an image. The human eye is an organ that reacts to light and has several purposes. As a sense organ, the mammalian eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors and is possibly capable of detecting a single photon. Similar to the eyes of other mammals, the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment of the size of the pupil, regulation and suppression of the hormone melatonin and entrainment of the body clock. Visual perception is the ability to interpret the surrounding environment by processing information that is contained in visible light. The resulting perception is also known as eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in Linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science. Light entering the eye is refracted as it passes through the cornea. It then passes through the pupil (controlled by the iris) and is further refracted by the lens. The cornea and lens act together as a compound lens to project an inverted image onto the retina. The retina consists of a large number of photoreceptor cells which contain particular protein molecules called opsins. In humans, two types of opsins are involved in conscious vision: rod opsins and cone opsins. (A third type, melanopsin in some of the retinal ganglion cells (RGC), part of the body clock mechanism, is probably not involved in conscious vision, as these RGC do not project to the lateral geniculate nucleus but to the pretectal olivary nucleus.) An opsin absorbs a photon (a particle of light) and transmits a signal to the cell through a signal transduction pathway, resulting in hyper-polarization of the photoreceptor. Rods and cones differ in function.

Excellent information, except that a concave lens is thinner in the middle and thicker around the edge. The simulated image at 2:40 is inaccurate because it shows a thicker middle/thinner edge, which is the definition of convex.

Thanks for that it really did help me to do my homework!

Muscular destropy have any remedy?

u just great and great my regards

great video. I wished you would`ve titled it refraction though so it would have been easier to find. Thanks.

it'd be much better if you stated that the lens was the one with the incorrect shape, as the eye shape really doesn't affect the placement of the focal point, whereas the shape of the lens does. If the lens is too thick at a relaxed state then the focal point falls in front of the retina, if the lens is too thin at a relaxed state then the focal point falls behind the retina.

Actually incorrect. The cornea does way more focusing then the lens does. So a misshapen cornea causes the lens to be unable to compensate, and hence focus wrong.

2:02 if light focuses precisely on the retina then all colors should combine at the same point and make white and everything would appear white color to us, i think it should focus slightly front of retina(1:18) so different wavelentgh light waves can activate different cones to make 2D image of object

@supertubemind

3 жыл бұрын

You are confused. If the light coming in is white, it would be perceived as white. If the colour is not white, eg looking at a coloured object, then the three cones would detect the different primary colours but these would be in different amounts and they would recombine to form the colour of the object and not white light. Your attempt to redesign the eye is misguided.

Grass is a plant with narrow leaves growing from the base. A common kind of grass is used to cover the ground in a lawn and other places. Grass gets water from the roots in the ground. Grass is usually pigmented with the colour ‘green’. Grasses are monocotyledon, herbaceous plants. The grasses include the "grass", of the family Poaceae (also called Gramineae). Also sometimes it is used to include the sedges (Cyperaceae) and the rushes (Juncaceae). These three families are not closely related but belong to different clades in the order Poales. They are similar adaptations to a common life-style. The true grasses include cereals, bamboo and the grasses of lawns (turf) and grassland. Uses for graminoids include food (as grain, sprouted grain, shoots or rhizomes), drink (beer, whisky), pasture for livestock, thatching thatch, paper, fuel, clothing, insulation, construction, sports turf, basket weaving and many others. Many grasses are short, but some grasses, like bamboo can grow very tall. Plants from the grass family can grow in many places, even if they are very cold or very dry. Several other plants that look similar but are not members of the grass family are also sometimes called grass; these include rushes, reeds, papyrus, and water chestnut. Grasses are an important food for many animals, like deer, buffalo, cattle, mice, grasshoppers, caterpillars, and many other grazers. Unlike other plants, grasses grow from the bottom, so when animals eat grass they usually do not destroy the part that grows. Without grass, dirt can wash away into rivers (erosion). Graminoids include some of the most versatile plant life-forms. They became widespread toward the end of the Cretaceous. Fossilized dinosaur dung (coprolites) have been found containing grass phytoliths (silica stones inside grass leaves).[Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type. Grass is a valuable source of food and energy for many animals.Lawn grass is often planted on sports fields and in the area around a building. Sometimes chemicals and water is used to help lawns to grow. People have used grasses for a long time. People eat parts of grasses. Corn, wheat, barley, oats, rice and millet are cereals, common grains whose seeds are used for food and to make alcohol such as beer. Sugar comes from sugar cane, which is also a plant in the grass family. People have grown grasses as food for farm animals for about 4,000 years. People use bamboo to build houses, fences, furniture and other things. Grass plants can also be used as fuel, to cover roofs, and to weave baskets. n English, the word "grass" appears in several phrases. For example: "The grass is always greener on the other side" means "people are never happy with what they have and want something else." "Don't let the grass grow under your feet" means "Do something". "A snake in the grass" is about a person that will not be honest and will trick others. Grass is sometimes used as a slang term for cannabis (also called pot, weed, or marijuana)
